I added Stan's Notubes sealant to my Vittoria Open Corsa tubulars per the recommended amount (50-60 mL). I know this is added weight and increases rotational weight, but considering some of the roads I will use these on for training/racing, it's a good idea.

It seems as if 50-60 mL might be overkill for 700x23c tubular tires. Is this was people have used in past? Just curious what other opinions are. Thanks!

It will only be effective (if at all) for the first couple of months. After that it'll be just dead weight.

Keep in mind as well that you'll need to keep that tyre inflated and in service (as in keeping it rollng) if you don't want a lump of cured latex at the lowest point of the unused tyre or, even worse, an inner tube stuck together internally with solidified latex....

I have had Caffélatex sealant in a pair of tubulars for about 16 months now (I should ride them more I know) and much to my surprise it is still very much liquid. I have no experience with the Stan's, but the Caffélatex stuff seems to stay liquid for quite a while.

I used Stan's to seal a fairly large puncture caused by a Sheetrock screw in a Conti GP4000. It's right at the peak of the tread too and I didn't think it would even seal initially. Well, it sealed and is still going and will hold 90-100psi for weeks at a time between being used.

I purchased 240ml of Continental Revo Sealant. I plan to use it on Hutchinson Fusion 3 23mm Tubless tires as advance puncture prevention. There is a trade off between weight and puncture repair ability. Also the less volume the tire the less Sealant required. What range of tire sealant is recommended for this sealant and tire combination?

I used Stans before, but have since switched to Orange based on positive reviews. Haven't had a chance to try it though as yet! A good option to consider though, as I haven't heard anything bad about it.

I've had 3 instances where Stan's failed to plug a flat tire, but all 3 cases the tire was already pretty heavily damaged. Conti Competitions (for me anyways) seem to lose a lot of tread just through normal riding, especially the rear, and just wears down to a point where failure is inevitable. Longest I've gotten out of a new tire is 1 year, shortest is just 2 months.

But for those 3 failures, Stans also saved me about 8 times. But it's enough to get me thinking about going back to clincher wheels just so I can swap a tube (or patch it) and keep riding. Such a bummer to have to cab it back home and have the rest of the ride wasted
